Communication Manager: Manual Date/Time Change Instructions for Daylight Saving Time Adjustments.

Several localities worldwide plan to extend their Daylight Saving Time schedule in 2007. Others have announced plans to do so later. Avaya Communication Manager can automatically adjust for Daylight Saving Time; however, this is based on the built-in schedule dates for Daylight Saving Time for each locality. If there is a change in these schedules for a particular locality, Avaya Communication Manager may require software updates.

In some cases, Communication Manager updates may not be available soon enough to accommodate support of changing Daylight Saving Time start and end dates. This document provides instruction on how to manually make these changes.  

Example 1: US and Canada Changes – early 2007

Example 2: New Zealand Changes – late 2007

The Following steps must be followed in the exact order specified to be used as a manual procedure for S8xx0 Series Servers running releases of Communication Manager that do not have a Daylight Saving Time patch available and have not upgraded:

Manual Procedure to Change Time for Start of Daylight Saving Time: [1]

1. After the Daylight Saving Time start date per the new rules occurs:

a. If the Server is synchronizing to a network time server, use the following steps to disable synchronization.

NOTE: Once synchronization with a network time server is disabled it is possible to experience clock drift on the S8xx0 series server. Clock drift occurs when the time on the server slowly deviates or drifts from the correct time. If the clock drift becomes too great the server time should be set to the correct time manually (see below for instructions on setting the time manually).

i. Select Configure Server from the Maintenance Web Interface.

ii. Click the Continue button to proceed until a Configure individual services radio button is available.

iii. Select the Configure individual services radio button and click the Continue button.

iv. Select Configure Time Server.

v. Note the IP address or host name of the network time server and copy it to a safe place. This is needed when the synchronization to the network time server is enabled again. Select the This computer synchronizes with the duplicated server radio button on duplicated servers and the Use Local Clock radio button on non duplicated servers. It is important to note that these choices might be different depending on the release of Communication Manager Software. As long as the choice other than Use these Network Time Servers is selected, meaning the Use these Network Time Servers radio button is NOT selected, the synchronization with network time servers will be disabled.

vi. Click the Change button and a success message should be displayed.

vii. Click the Close window button.

b. Manually set the server time to be correct.

NOTE: When setting the time manually via the Maintenance Web Interface on Servers running Communication Manager 3.1.2 there is a known issue that can cause the server to perform a reset! To fix this known issue contact your technical support organization and request patch 12768 or any combo patch or Service Pack (Service Pack 12866 or later 3.1.2 Service Packs) containing it.

i. Select Server Date/Time from the Maintenance Web Interface

ii. Set the time on the server to the correct time for Daylight Saving Time and click the Submit button.

REPEAT THIS PROCEDURE ON ANY ESS or LSP SERVERS ALSO AFFECTED BY THE DST EXTENSION.

No further changes are required until after the Daylight Saving Time start date using the old rules occurs.

NOTE: Do NOT enable synchronization with the network time server during this interval.

2. After the Daylight Saving Time start date using the old rules occurs, the time is automatically adjusted forward one hour on the Server. NOTE: It is very important to let this transition occur and let the Server make the automated time adjustment before taking additional steps!

a. At 2:00 A.M. the time will be set forward automatically to 3:00 A.M. on the server. NOTE: At this point you cannot set the time back! You must wait until the server time is 4:00 A.M. or later before trying to set the time back! After waiting at least on hour, manually set the time to be correct.

NOTE: When setting the time manually via the Maintenance Web Interface on Servers running Communication Manager 3.1.2 there is a known issue that can cause the server to perform a reset! To fix this known issue contact your technical support organization and request patch 12768 or any combo patch or Service Pack (Service Pack 12866 or later 3.1.2 Service Packs) containing it.

i. Select Server Date/Time from the Maintenance Web Interface.

ii. Set the time on the server to the correct time for Daylight Saving Time and click the Submit button.

b. If synchronization to a network time server was previously disabled in step 1, use the following steps to enable it.

NOTE: When enabling synchronization to a network time server via the Maintenance Web Interface on Servers running Communication Manager 3.1.2 there is a known issue that causes the synchronization to fail! To fix this known issue contact your technical support organization and request patch 12868 or any combo patch or Service Pack containing it. If the patch is applied while synchronized to a network time server, the Change button on the Configure Time Server page must be clicked to activate the fix.

i. Select Configure Server from the Maintenance Web Interface

ii. Click the Continue button to proceed until a Configure individual services radio button is available

iii. Select the Configure individual services radio button and click the Continue button

iv. Select Configure Time Server

v. Select the Use these Network Time Servers radio button and provide the Network Time Server information.

vi. Click the Change button and the message Successfully added NTP information should be displayed.

vii. Click the Close window button.

Manual Procedure to Change Time for End of Daylight Saving Time: 2
